weird problem with USB connection - LG Optimus Black

hi (sorry for my bad english),
I've been using CM10 without problems (updates via OTA included), MTP & mass storage modes working properly.
Until one day stopped working!
- The mobile charges fine, both USB and wall charger.
- I installed CM10 from scratch, with all the wipes, even I tried with another SD and does not work.
- When connecting the mobile by USB (Windows & Ubuntu) recognizes the device and the modem but no storage.
- From ubuntu console.... "adb devides" command do not recognize it.
- In the mobile shows no notification, no debugging or usb.
but ...
- From the recovery CWM ... I can mount the sd by usb and it works fine! adb also recognize the device!
- Recognizes the phone SmartFlash Mode S / W in windows.
so its not hardware relating? that might be happening?
thank you very much
PD: FIXED! flash official ginger bread with SmartFlash and CM10 again... and now works usb storage.

Hey,
I have the same problem as you, do you have a link to the official ROM, I've been searching for a while and I don't find any >_<
thanks
EDIT:
Finaly I found a link ^_^

[Q] USB Debugging/Mass Storage Mode connection to computer issue

Hello folks,
I'm facing this "please insert a disk" issue when connecting my Note to computer via USB Debugging mode / Mass Storage Mode.
I'll let screenshots in the attachment explain itself. #1 shows the screenshot of devices menu when the phone is plugged into the computer in DEBUG mode; #2 shows the screen after I've clicked "connect USB storage" from the drop-down list of the phone; #3 shows what happens when I try to open one of the two "removable disks".
MTP mode works fine, as well as Kies connection. As I finally started exploring the potential of Android platform, I realized that MTP and Kies connection are the most useless connection options for me, and I'd rather leave it in debug mode all day. So has anybody experienced this issue, or had any suggestion on the solution?
As always, many thanks in advance, and many thanks button clicks afterward!
p.s.,
Desktop OS: Win7 Pro X64 SP1
Note: 2.3.6 Stock LB1 Open Germany Firmware, CF rooted LB1 kernel.
Also, I should have all the latest official device driver from Samsung, as I have the latest version of Kies installed (and I discovered a driver folder under Kies' installed location). I'm not so sure about adb driver, but I was able to find the Note to be listed under devices by typing "adb devices". So.. I don't know where could've gone wrong.
Help anyone?
This really sounds weird... I was facing problems of the Galaxy Note not being detected on several Windows7 32/64-Bit SP1 computers as well but this was gone after I installed SAMSUNG_USB_Driver_for_Mobile_Phones.
You are right - from all that i know all required drivers should be available when KIES is installed on your system. Whatis even more strange is that your device seems to be detected as two partitions are available and are displayed in Explorer...
So I would test the following:
- check if your device manager lists any unknown devices
- Uninstall KIES and try to find the SAMSUNG_USB_Driver_for_Mobile_Phones and install those
- check all available USB ports and see if this solves the problem
- try another USB cable
- make sure your (external) SD card is formatted with a Windows compatible file-system e.g. FAT32
Hope this is helpful and helps solving your problem.
Thanks for your reply!
My device manager basically listed all the drivers/devices associated with the phone:
My Device manager shows devices:
Samsung Android Composite ADB interface
Android UMS Composite USB device (x2)
SAMSUNG Android USB Modem
USB Mass Storage Device
USB Mass Storage Device (Android)
I've attached the screenshot when all the drivers being installed when the phone is firstly connected to the computer. Also in the device manager, everything shows "this device is working properly"
I then decided to test with another Note of my friend's (On the same computer). Her Note has no SD card in it, and is completely stock ROM non-rooted LA4 Open Germany firmware. The same thing happened.
One thing worth mentioning: Yesterday, this worked only for once. When I initially encountered this issue, I restarted my computer, and boom, my phone was connected in Debugging mode! However, once disconnected, and I tried to connect it to the computer again, this issue came back. And afterward, no matter how I restart my computer, the phone won't get connected.
I also tried all USB port (USB 2.0 and 3.0), three different cables (2 of them are Samsung OEMs) and failed to address the issue.
I'm nearly exhausted but I will never give up, as this is my only computer and my only phone (haha), and without solving this issue, I'm never gonna be able to view the phone as a USB storage and easily transfer the file from my computer to the phone.
I'm going to try the last thing that I haven't done from the list you posted:
- Uninstall KIES and try to find the SAMSUNG_USB_Driver_for_Mobile_Phones and install those
I believe that I can keep the driver folder in the Kies' folder, as I believe those are the newest Samsung driver, given that the Kies was the latest release version.
So far, I can only conclude that this issue is not related to specific phone but the Windows 7.
And thank you for your help btotaku!
If anyone has any insight into this issue, please help me. Thumbs up for you!
BTW, I was able to extract both SAMSUNG_USB_Driver_for_Mobile_Phones.exe from under Kies' installation path under Program Files x86 folder, and an uncompressed folder of all kinds of drivers for Samsung device, called "USB Drivers".
And looks like I was wrong. The newest version of SAMSUNG_USB_Driver_for_Mobile_Phones I had was 1.4.8. While the driver that came with the newest Kies was 1.4.103
I'll post back soon
Reinstal Windows on your PC bro.
Problem fixed.
is that your internal memory or the sd card?
Same thing happens either with SD card in the phone or not

Cant mount CD into PC

Hi all,
I'm currently using MIUI 2.1a released in this thread. http://forum.xda-developers.com/showthread.php?t=1588360
I connect my phone into pc and toggle on the mount usb storage but i cant see the external drive in my computer.
I tried it with diffrerent PC's and reflashed the same ROM result is the same. Any ideas?
PS:It was working before.(with this ROM) after a certain thing(dont know what) it happened.
Try reinstall the LG-drivers from the LG-page.
Could try usb debugging and check to see whether your PC even recognises ur phone using the command "adb devices".
Then if ur phones is recognised it should install drivers automatically (if ur on windows 7).
If not then as @pacos1 said, install the LG United Mobile Drivers either through the lg P970 support page or through their update module.

please dont use any USB hubs...connect it to the USB port on the motherboard side....normally on the rear side for the Desk tops.....on the laptop all ports are directly connected normally...
secondly, what is your config? ROM?Kernel?please state your current configuration which can allow others to understand the situation.
Thanks
yeah i dont use usb hub i connect it directly i tried it on my laptop but its not working
my o2x dont say that usb debugging is connected it only charge
im on stock GB now 2.3.4 v20g
Don't want to hijack this thread, just got the same problem. (Not a complete noob here, rooted lots of different devices)
Bought a used 2x today. Froyo 2.2.2 german stock on it.
It just doesn't show the prompt that USB is connected
Tried:
- LG Mobile Driver from version 2.x.x up to 3.7.2
- on Win7 32 bit, Win7 64bit, Win XP 32 bit on various USB ports
- LG PC Suite obviously doesn't connect too
- checked/unchecked USB debugging, USB mass storage and all the obvious settings
- tried different cables
Would be really great if someone experienced could point us in the right direction.
EDIT:
After lots and lots of google I found out about a menu when dialing: 1809#*990#
With these options available:
CP Image Download
FET Disable
FET Enable
AP UART
CP UART
AP USB
CP USB
CP UART gave me at least a life sign once by saying that Windows wasn't able to recognize the device.
Is this issue really unsolvable?
Sorry for the bump, but I got some update.
when dialing the above mentioned 1809#*990# in the Port menu, switching from default AP USB to AP/CP UART gave me life signs.
After switching to AP UART I linked the Unknown device driver to lgusbdiag.inf located in C:/ProgramFiles(x86)/LG United Mobile Driver.
Suddenly it started installing it and is now recognized as: LGE Platform Android USB Device.
Once disconnected I lose USB again, I'm able to recreate the first steps though even in default AP USB mode by now.
The only thing I need USB for is for flashing a custom recovery but the only thing I don't have is ADB somehow : / Clockwork telling me: device not found.
Any help on this one?
any idea guys about my problem?
Have you tried my method?
After manually installing drivers with CP UART on, switching back to default permanently enabled access with default AP USB settings as well.
i tried that but it only charge
theres a weird thing in my cp when i switch to cp uart my o2x says it charging even i dont connect it to my pc or charge it
Ap uart - p990 / p999
I have LG P999. rooted and cyanogen.
None of the special DTMF dialing # codes is not working (also code changed from 990 to 999) (i sow some other in another posts)
is anybody know a way to change to AP UART by software (with eclipse...)
or with a special cable?
i need to use AP UART - meaning to have a serial com in AP(app).
Thanks,
Tamir
guys,
Have you tried to install MyPhone Explorer and try the same....it can connect your device via wifi,USB or Bluetooth....so some way should work....
any Android version above Froyo(included) should work....I use this always...one of very useful and bug free apps.
Try it

[Q]Does not show GT-N7000 when connected to pc

hi, when Rocket Rom 7 (ics) came out, i installed it. after doing this, when i connected my phone to the pc, the system detects the phone as Samsung_android and shows 2 removable drives in the system. however, if you click on them they dont work
it no longer detects my phone as GT-N7000
what i have noticed: when i connect the usb cable, the phone doesnt show "MTP connection" anymore... instead, it shows USB connected.
what has been done:
flashed rocket rom 10, nogo
reinstalled kies: nogo
reinstalled win7 (yes i actually did that even tho testing on other pcs showed the same issue)
the phone still charges and the only way i can connect my phone to d pc to view files is by clicking "usb storage"
any advice on this?
Uninstall kies, and just install driver (find latest from toolbox on my signature)
use different USB port, and dont use any extensor cable to connect device.

hi bro... didnt work... i dont think its the driver... its the phone... coz i tested another note, its working fine
My Galaxy Tab has similar issues. I believe it would be due to the architechture of the ROM forcing you to have to mount your device to your computer before being able to load the Device Internal SD, and the External SD.
Click USB Storage when it shows, this should pop up a window which has a Lil android dude, and USB Storage Message with a button stating 'Turn on USB Storage'. After clicking it, you can click 'Turn Off USB Storage' to unmount the device.
thanx for that.. hehe.. i stumbled across it the other day.. at least i can transfer files... but just dont like the fact its not showing...

[Q] Can't connect my Note in MTP usb mode

Hello guys! I'm running Ultimate JB rom since v4 and since then I can't connect my phone USB in MTP mode. I tried many things like USB mode switcher from market, tried running manually script: setprop persist.sys.usb.config mtp,adb - but no success... It just connects in Mass Storage mode. After reboot it just goes in Mass Storage mode again! Mass storage mode works fine, but it's annoying to go and push the button to connect and then safely remove from computer and... Yeah, the process is slow and annoying for me.
Now im running Ultimate XXLSA JB v5, can somebody help me to fix MTP? Thanks in advance!
Same Prob
+1
Even I have the same prob .. But I am in Robbie's Alliance betA 1.1 ROM ... Pls help!
